This may be sacrilege here on TB but you do not need a strong bass line on all songs all of the time. This is a foreign concept to many of genres that many of you play but if you play certain types of music, you as the bassist will spend a fair amount of time "playing" rests. I play in a church band and church music often has the bass sitting out the opening or dropping out for a section here or there. Some time ago someone here posted a link to a humorous video that described how to write modern praise and worship music. It went on for some length but the only part we bassists in the praise and worship music club noticed was a line thrown in almost at the end, the all too true: "Oh, yeah, and don't bring in the bass until measure 53!" Kinda how life can be for a church bassist although to be fair we are sometimes asked to play, gasp!, solos and we frequently do come in right at the beginning and play right the way through to the end.
If you have a Bass VI (and I do) and you know how to play it outside the normal bass box (I'm working on it) then you potentially have things you can do during those moments when a bass line isn't needed. For some reason my church has trouble finding lead guitarists and that is the reason I got the VI. There are times when a lead guitar is wanted but a bass is not and the VI would let me play lead. Of course, since then a couple of guitarists have shown up but you get the point. Whether your genre traditionally has the bass sit out occasionally or not, if you want to take your music and your genre in a new direction a Bass VI would let you do that while still keeping you in the game. Something to think about. At the end of the day a Bass VI is just a short scale, six string bass with unusually tight string spacing. You can tune them as low as a B if you want to run the traditional six string bass BEADGC tuning. The spacing takes some getting used to but I, who was never able to adapt to a fiver before, found that I could adapt to a Bass VI and now that I have done so, I have no trouble with fivers any more either. Go figure. You learn to play fingerstyle on a tight spacing, you learn to play with a pick, you learn to incorporate another string's range into your playing, and suddenly you are a new bassist. You may not play one all the time but a Bass VI could be the perfect spice to punch up some of what you play.
